About

CalorieMetric — built to stay free, forever.

CalorieMetric is a lightweight calorie tracking tool designed for people who want accurate nutritional awareness without the overhead of signing up for yet another app.

What it does

You enter your stats once — age, height, weight, activity level — and CalorieMetric calculates your maintenance calories using the Mifflin-St Jeor equation, the gold standard formula used by nutritionists worldwide. Then you log your meals in plain English and we estimate the calories using AI. Build a daily streak by staying within your goal.

Who it's for

Anyone who wants a simple, honest answer to "am I eating too much or too little?" — without subscriptions, paywalls, or being asked to enter a credit card. Whether you're trying to lose weight, gain muscle, or simply stay stable, CalorieMetric gives you the number you need.

Our principles

• Free forever. No premium tier, no freemium bait-and-switch.
• No account required. Your data lives in your browser's localStorage, not our servers.
• No personal data collected. We don't know who you are and we prefer it that way.
• Fast. No app store download, no install, no wait. Open the URL and start.

The technology

CalorieMetric is built with Astro JS, a modern static site framework. Calorie estimates for meals are powered by AI (Groq / Llama) — your food queries are sent to the API but not stored or logged on our end. All your personal data (goals, logs, streaks) stays exclusively in your browser.
